ポンプの制御装置。 A fuel pump comprising: a power transistor interposed in a current supply circuit to a motor of the fuel pump; and duty control means for duty-controlling conduction/non-conduction of the power transistor based on a duty ratio calculated from a required supply amount of fuel. In the control device, overcurrent detection means detects whether or not an overcurrent is flowing through the motor based on a divided voltage of a voltage dividing resistor inserted in series with the motor; A disconnection detection means for detecting the presence or absence of a disconnection in the energized circuit, an alarm means for issuing an alarm when an overcurrent is detected and a disconnection is detected, and a duty ratio reduction correction means for decreasing the duty ratio when an overcurrent is detected. A fuel pump control device characterized by:
